SEPARABLE COLLAR-BUTTON.

SPECIFCATON forming part of Letters Patent No. 427,699, dated May 13, 1890.

Application filed March l0, 1890. Serial No. 343,336. (No model.)

To all whom it may concern:

Be it known that I, ADAM LOOs, of Toledo, in the county ot` Lucas and State of Ohio, have invented certain new and useful Improvements in a Separable 'Collar-Button; and I do herebyV declare that the following is a t'ull,elear, and exact description of the inven tion, which willenable others skilled in the art to which it appertains to make and use the same, reference being had t0 the accompanying drawings, and to the letters of reference marked thereon, which form partof this specification.

My invention relates to an improved separable collar-button5 and it has for its object the production of a button of this class which will be of simple construction and whose parts can be readily put together and taken apart.

The invention will iirstbe described in connection with the aceompanyin g drawings, and p then pointed out in the claim.

Figure l of the drawings is a vertical seetion of the button, showing the key in the keyway prior to being turned into the recess in the inner tube to lock the parts together. Fig. 2 is also a vertical seetion of the button, showing the parts locked together. Fig. 3 is a horizontal section of the button, taken on the line .fr x in Fig. l. Fig. et is a perspective view of the inner tube.

A is the base-plate or shoe stamped up into a slightly-concave form from any suitable metal.

I3 is the outer tube of t-he shank, which is formed integral with or suitably attached to a disk O, held in place within the shoe by the overlapping edge of the latter, the disk having a central opening c where the tube joins it. Y

D is the inner shank-tube, which is tted within and secured to the tube B. As will be seen in Fig. et, it is slotted longitudinally throughout its length, as at d, to form a keyway, and in its inner end, to one side of slot d, there is formed a recess r, for a purpose hereinafter stated. The innertube is somewhat shorter than the outer tube, but their outer ends are flush, and a eoil-spr1ng E bears at one end against the inner end of tube D and at its other end against the shoe A, it being held in place by the outer tube, as seen in Figs. l and 2.

F is the cap, struck up from any suitable metal into a hollow half-round form, and G is a disk covering the open side of the cap, it being secured to overlapping fianges on the latter. In the center of this disk there is a perforation g, et just suiiicieut size to permit the entrance therethrough of the outer end of the shank, as seen in Fig. 2. Within the cap is secured the outer end of a solid post Il, on the free end of which is formed a laterally-projecting lug 7L, termed the key The post II is of a size to fit neatly within the inner tube of the shank.

In putting the separable parts of the button together the post is inserted within tube D, with the key 7L in the keyway d. The post is then pressed inward until it 'comes into contact with and compresses the spring, by which time the key will have passed below thelower end of the inner shanletube, and then the post is turned until the key registers with the recess r in said tube, when the spring will force the post outward, carrying the key into the recess, and thus locking the parts together. The manner of separating the parts is obvious without description.

It will be observed that in my improved collar-button the shank presents an outer surface unbroken by slots or perforations of any kind. Furthermore, the post snuglyts within the shank, and when the parts are locked together the outer end of the shank is irinly held within the cap, thereby rendering the part-s rigid with respect to each other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a separable collar-button, the combination, with the shoe, of an outer shank-tube secured to the shoe, an inner shank-tube, shorter than the outer tube, secured within the latter and slotted and recessed, as described, a spring bearing against said inner tube, a hollow cap provided at its rear side myown I hereby afiX my signature in pres- Wit-h a disk perforated to receive the end of ence of two Witnesses. the shank, and a, post secured within the cap and provided 011 its free end with a lat- ADAM LOOS' 5 eralIy-projeoting key, substantially as de- Vtnesses:
